ACT 2002 Acura RSX XT/Race Rigid 6 Pad Clutch Kit
ACT AR1-XTR6 is the hardest-hitting single-disc clutch ACT builds for the K-series Acura RSX. It is for a drag car, a time-attack build or a turbo K20 making enough power that a sprung race disc has started to break or slip. Our listing is titled for the 2002 RSX, and ACT catalogs the same kit for the 2002-2006 RSX, 2002-2011 Civic Si and 2004-2008 TSX. If you are shopping because your RSX flares rpm in third and fourth under boost, or because a damper hub came apart on the last disc, read on. If the car is a daily driver, this is probably more clutch than you want.
ACT rates AR1-XTR6 at 435 ft-lb at the crank, 128 percent over the factory clutch. Two parts make that number. The H024X Xtreme pressure plate uses ACT's own diaphragm, heat treated in four stages, to raise clamp load and keep deflection low so clamping force holds up at high rpm. The 6214010A disc is 214 mm (8.4 in) across with six ceramic pads riveted to a heat-treated chromoly hub that has no damper springs at all.
No springs means less rotating weight, quicker shifts and nothing in the center to fatigue on repeated launches. It also means every firing pulse and every clutch dump goes straight into the transmission. ACT lists the feel as moderate to heavy pedal effort, aggressive engagement and increased gear rattle, warns that a rigid hub may increase input-shaft spline wear, and recommends this kit for race use only. That is the honest trade, and it is why ACT also sells the sprung AR1-XTG6 with the same plate.
A true slip test is simple: fourth gear, low rpm, full throttle, and watch whether the tach jumps without the car pulling harder. Rule out the cheap causes first. Bleed the hydraulic system, check that the pedal returns fully and confirm no rear main seal or transmission seal oil is on the bellhousing, since oil will ruin any disc. Our slipping diagnosis guide explains reading rpm against speed, and flare versus slip helps if you are unsure what you are feeling. If the engagement point has moved, the engagement height guide covers what that means.
The AR1-XTG6 shares the 435 ft-lb rating and the Xtreme plate but adds a spring center, which ACT describes as more drivable. Pick the rigid AR1-XTR6 when the car is trailered, raced most weekends, or has already destroyed a sprung hub. For a street car with moderate power, step down to ACT's full-face street kits instead.
ACT lists AR1-XTR6 for the 2002-2006 Acura RSX base and Type-S (K20A2, K20A3, K20Z1), 2002-2011 Honda Civic Si with the K20, and 2004-2008 Acura TSX 2.4L (K24A2) 6-speed. The disc uses a 1-1/32 inch input spline. Engine swaps, JDM transmissions and mixed flywheels all change what bolts up, so check the part number on your current clutch or send us the year and VIN and we will confirm before it ships. More K-series clutches and kits are in our clutch and rebuild kit collection.
The box includes the H024X pressure plate, 6214010A disc, RB313 release bearing, AT78 alignment tool and PBNA004 pilot bushing. A flywheel is not included. A ceramic pad disc needs a flat, freshly surfaced face, so most builders pair this kit with a lightweight flywheel such as the ACT 600125 Prolite. Use the alignment tool, run the pressure plate bolts down in a star pattern, and bleed the system fully; a braided master and slave line kit helps pedal feel with the heavier plate. ACT says race discs need only a few hard slips to lap in. Refill the transmission with Honda MTF.

ACT lists AR1-XTR6 for the 2002-2011 Honda Civic Si with the K20, along with the 2002-2006 RSX and 2004-2008 TSX. If the engine or transmission has been swapped, send us the year and VIN or the part number on the old clutch and we will confirm fitment.
ACT recommends this kit for race use only. Engagement is aggressive, pedal effort is moderate to heavy and gear rattle increases because the hub has no damper springs. A daily-driven RSX is better served by a sprung disc or a full-face street kit.
Both use the same Xtreme pressure plate and carry the same 435 ft-lb rating. AR1-XTG6 has a spring-centered 6-pad disc that damps driveline shock, while AR1-XTR6 is solid hub, lighter and harsher, and may increase input-shaft spline wear.
No. The kit includes the pressure plate, 6-pad rigid disc, release bearing, pilot bushing and alignment tool. Resurface your flywheel or replace it, for example with an ACT XACT flywheel made for the K20.
ACT says its race discs usually need only a few hard slips to lap the surfaces in before normal driving or racing. Avoid overheating the clutch during those first engagements.
Refill the K-series manual transmission with Honda MTF to the fill plug, and use fresh DOT 3 brake fluid when you bleed the clutch hydraulics.
